IT IS MEANT TO BE INCLUDED BY # OTHER MAKEFILES. # The following variables (set by other Makefile components, in the # environment, or on the command line) are used: # # BUILD The architecture dependent directory, # e.g. `$(TOP)/builds/unix'. # # OBJ_DIR The directory in which object files are created. # # LIB_DIR The directory in which the library is created. # # INCLUDES A list of directories to be included additionally. # Usually empty. # # CFLAGS Compilation flags. This overrides the default settings # in the platform-specific configuration files. # # FTSYS_SRC If set, its value is used as the name of a replacement # file for `src/base/ftsystem.c'. # # FTDEBUG_SRC If set, its value is used as the name of a replacement # file for `src/base/ftdebug.c'. [For a normal build, this # file does nothing.] # # FT_MODULE_LIST The file which contains the list of modules for the # current build. Usually, this is automatically created by # `modules.mk'. # # BASE_OBJ_S # BASE_OBJ_M A list of base objects (for single object and multiple # object builds, respectively). Set up in # `src/base/rules.mk'. # # BASE_EXT_OBJ A list of base extension objects. Set up in # `src/base/rules.mk'. # # DRV_OBJ_S # DRV_OBJ_M A list of driver objects (for single object and multiple # object builds, respectively). Set up cumulatively in # `src/<driver>/rules.mk'. # # CLEAN # DISTCLEAN The sub-makefiles can append additional stuff to these two # variables which is to be removed for the `clean' resp. # `distclean' target. # # TOP, SEP, # LIBRARY, CC, # A, I, O, T Check `config.mk' for details. # The targets `objects' and `library' are defined at the end of this # Makefile after all other rules have been included. # .PHONY: single multi objects library # default target -- build single objects and library # single: objects library # `multi' target -- build multiple objects and library # multi: objects library # The FreeType source directory, usually `./src'. # SRC := $(TOP)$(SEP)src # The directory where the base layer components are placed, usually # `./src/base'. # BASE_DIR := $(SRC)$(SEP)base # The build header file used to define all public header file names # as macro. # ifndef FT_BUILD_H FT_BUILD_H := $(TOP)$(SEP)include$(SEP)ft2build.h FTBUILD_CMD := else FTBUILD_CMD = $(D)FT_BUILD_H=$(FT_BUILD_H) endif # A few short-cuts in order to avoid typing $(SEP) all the time for the # directory separator. # # For example: $(SRC_) equals to `./src/' where `.' is $(TOP). # # SRC_ := $(SRC)$(SEP) BASE_ := $(BASE_DIR)$(SEP) OBJ_ := $(OBJ_DIR)$(SEP) LIB_ := $(LIB_DIR)$(SEP) PUBLIC_ := $(TOP)$(SEP)include$(SEP)freetype$(SEP) INTERNAL_ := $(PUBLIC_)internal$(SEP) CONFIG_ := $(PUBLIC_)config$(SEP) CACHE_ := $(PUBLIC_)cache$(SEP) # The final name of the library file. # PROJECT_LIBRARY := $(LIB_)$(LIBRARY).$A # include paths # # IMPORTANT NOTE: The architecture-dependent directory must ALWAYS be placed # in front of the include list.
